Description

Motor air intake dust filtration device
Technical field
The present invention relates to be assemblied in the dust filtration device of self-ventilated machine air inlet, be specially a kind of motor air intake dust filtration device.
Background technology
At present, self-ventilated machine is simple in structure with it, easy care, thereby the favor that noise is little and the little advantage that takes up space is subject to motor user has obtained generally application, and molecule in the cooling-air entering can cause damage to winding insulation in motor, affect electrical machinery life, therefore, the dedusting structure of self-ventilated machine and device, with and dust removing effects caused people's generally attention.Existing self-ventilated machine relies on air inlet that dust excluding hood is set to meet the instructions for use of clean cooling air mostly.Existing dust excluding hood structure is that several metafiltration nets are set at air inlet place, fills fine and close filter dirt material in the middle of filter screen, reaches certain filter dirt effect.But its complex structure, windage is larger, and dust enters rear easy obstruction filter screen, and not easy-clear, affects the inlet of cooling air, and then cooling effect is reduced, and this structural maintenance difficulty cost is high.
Summary of the invention
The present invention greatly, easily causes obstruction inconvenience to remove in order to solve existing self-ventilated machine dust excluding hood structure windage, and the not high technical problem of easy care and maintenance cost, provides a kind of motor air intake dust filtration device.
The present invention realizes by the following technical solutions: a kind of motor air intake dust filtration device, comprises a shell that is convex structure; One side of shell has air inlet, and the bottom of shell has air outlet, and air inlet is provided with protective cover; The position that enclosure and air outlet are adjacent is provided with the dust collecting trough of a upper opening, is fixed on dividing plate between outer casing inner wall isolated between dust collecting trough and air outlet by one; Dividing plate top is provided with a lower wind deflector, the air inlet place of shell extends internally and is provided with a upper wind deflector that is the convex structure matching with shell circular arc and is positioned at air outlet top, between upper wind deflector and outer casing inner wall, form air intake passage, the lower end edge of upper wind deflector is above lower wind deflector and gapped between the two; Dust collecting trough is connected with the dedusting mouth towards motor internal.
The present invention is arranged on the air inlet of motor, the air inlet of air outlet to alignment motor when installation.Wind deflector forms by upper and lower two, and the cavity (air intake passage) of upper wind deflector and shell composition, under the effect of centrifugal fan, imports the cooling-air of filtering first dirt by protective cover; The cavity of lower wind deflector and shell composition at cooling air through out-of-date; wherein particle dust is under centrifugal force and Action of Gravity Field; inwall along shell and lower wind deflector is slipped in dust collecting trough; the gap that the cooling air of filtering forms from upper wind deflector, lower wind deflector and shell enters motor, plays filtering and cooling effect.
Motor air intake dust filtration device of the present invention is simple in structure, and windage is little, easy care, and convenient maintenance, has greatly saved clean and maintenance cost, can be widely used in the filter dirt at self-ventilated machine air inlet place.

1-shell, 2-protective cover, the upper wind deflector of 3-, the upper wind deflector of 4-, 5-dust collecting trough, 6-dedusting mouth, 7-air inlet, 8-air outlet, 9-motor, 10-air intake gap, the upper air duct of 11-.
Embodiment
A kind of motor air intake dust filtration device, comprises a shell 1 that is convex structure; One side of shell 1 has air inlet 7, and the bottom of shell 1 has air outlet 8, and air inlet 7 is provided with protective cover 2; The inner position adjacent with air outlet 8 of shell 1 is provided with the dust collecting trough 5 of a upper opening, is fixed on dividing plate between shell 1 inwall isolated between dust collecting trough 5 and air outlet 8 by one; Dividing plate top is provided with a lower wind deflector 4, air inlet 7 places of shell extend internally and are provided with a upper wind deflector 3 that is the convex structure matching with shell circular arc and is positioned at air outlet 8 tops, between upper wind deflector 3 and shell 1 inwall, form air intake passage, the lower end edge of upper wind deflector 3 is gapped above lower wind deflector 4 and between the two; Dust collecting trough 5 is provided with the dedusting mouth 6 towards motor internal.
Air inlet 7 axis of shell 1 and air outlet 8 axis angulation a are 45 ~ 70 degree.
As described in Figure 1, the air inlet of dust filtration device of the present invention is positioned at a side, and air outlet is positioned at below.The air intake gap 10 that between the axis of the two, the gap at an angle and between upper and lower wind deflector and outer casing inner wall forms as seen from Figure 2.Air outlet is other is provided with dust collecting trough 5, for collecting the larger particle entering in dust filtration device; Air intake passage is connected with dust collecting trough 5 upper openings.Be circular-arc air intake passage and air intake gap 10 through the wind outside of protective cover 2 through one and enter motor internal.The upper wind deflector 3 that is convex structure is positioned at air outlet 8 tops, can prevent that larger particle from entering stator winding and rotor.
Shell 1 is shaped by light sheet bending or welding, and its inwall adopts arc transition, to reduce windage.
Protective cover 2 meets certain degree of protection requirement, and cooling air is carried out to ground floor filtering, and larger particle sand and dust are blocked in to outside motor.
Wind deflector is upper wind deflector 3 and 4 two formations of lower wind deflector.
Under shell 1 is interior, the bottom of wind deflector 4 is provided with dust collecting trough 5.
Dedusting mouth 6 connects by air duct on support 11 with dust collecting trough 5.
Dust by dust collecting trough 5, is avoided stator winding and rotor through specific upper air duct 11(on stator), from dedusting mouth 6(dedusting mouth towards motor internal) enter motor internal, then by fan, discharge outside motor together with cooling air.Dust is mainly the pollution of stator winding and rotor to the pollution of motor; and structural design described in employing the application; because dust can be avoided stator winding and rotor; be equivalent to dust and cold wind to separate; dust is walked around stator winding and rotor; cold wind is through stator winding and rotor, and then discharge in the lump, so play the effect of dedusting protection.
In examination as to substances reference diagram, be the annexation that has shown dust collecting trough and dedusting mouth, upper air duct is positioned at the housing exterior of motor, is connected after having walked around the stator winding of motor through dedusting mouth with motor internal always again.
